Causes and solutions for slow Internet access in Win7 system

First, the network itself's problems
The network also has peaks and valleys. Therefore, if the bandwidth is not large enough, it is likely that the Internet is slow due to network congestion, and it may be that the computer's broadband equipment has been attacked by hackers, resulting in network changes. slow.
Solution: Try to avoid the peak period during the Internet.
Second, may be a virus in the computer
Phenomenon: If the Internet access is fast, but after entering some websites or downloading some software and causing the network speed to become very slow, then there may be a website or software. With a virus, then your computer is poisoned, causing the virus to take up a lot of broadband.
Workaround:
1, you can use anti-virus software to scan the computer and clean the virus in time;
2, if the normal mode anti-virus has no effect, then enter the safe mode before the computer is turned on, and then use Anti-virus software for full scan;
Third, the wireless network was smashed by others
Phenomenon: The home uses wireless Internet access, before the Internet speed is very fast, the latter is inexplicably slowed down, if there is no poisoning, then It may be that someone else has smashed the net.
Workaround: You can encrypt the wireless network, or strengthen the password modification process, etc.
Fourth, clear the arp cache
If the arp cache list is too long, it will affect the speed of the Internet, too long cache The list will take up a certain amount of memory space, resulting in slow operation, which will cause the computer to go slow.
Workaround: Clearing the arp cache can alleviate the slow Internet access.
5. Broadband bandwidth is too small.
Phenomenon: If many people share a broadband line, the bandwidth is small, and the network speed is inevitable. It will be slow, if you need to find a network provider to increase bandwidth. Or when sharing bandwidth, someone downloads things in P2P software, then the speed of other users will be greatly reduced, approaching 0kb/s.
Workaround: Increase bandwidth, or use the switch to divide the bandwidth equally.
Six, the computer configuration is too low caused by the phenomenon of
: the computer configuration is too low, resulting in higher running software configuration, the program response is slow, the computer is too old, resulting in slow system response, which affects the Internet speed .
Workaround: It is recommended to update your computer configuration.
Seven, by lifting the windows system default limit of 20% speed increase operating speed
each windows system will have a 20% network speed limit, we can release it
